Figure I is a top or plan view of a tractor embodying the features of my invention. Fig. 11 is a top or plan view of the rear portion of the tractor, the attachment being shown in dotted lines. Fig. Illis a side elevation of the parts shown in Fig. II, the attachment being shown in fulllines and the single steering wheel being shown in dotted lines. r p

The tracbul comprises a pair of front ground wheels 1 secured to the axle 2, the ground Wheels: being supplied with suitable power is transmitted to impart rotation to the said ground Wheels from the engine oi the tractor, as will hereinafter more fully appear. The tractor frame comprises longitudinal side sills 4 and l extending from front torear of the frame, and also comprises suitable cross members uniting said sills at the front andrear ends and intermediate of their ends. The tractor frame is supported at its rear end, when the trac- Specification of Letters Patent.

tractor frame by a king bolt 8. The fifth wheel member (5 is also provided with a laterally projecting arm 9 to which the con necting rod 10 of the tractor steering mechanism is piYoted. The connecting rod 10 err-- tends forwardly from the location of the steering wheel 5 to a crank 11 operable by a steering shaft 11 to which the crank is geared in any suitable manner. The steering shaft 11 is provided with a hand wheel 12, by which said shaft may be rotated to impart longitudinal movement to connecting rod 10 for the purpose of causing the steering wheel 5 to direct the course of the tractor when it is propelled on the ground. Adjacent to the steering shaft 11 is a drivers seat 13 that is mounted on the tractor frame in any suitable manner.

ll designates an engine or motor of any suitable description carried by the tractor frame to'supply the necessary power for operating the tractor.

l5 designates a jack shaft operable by the engine M, said jack shaft being provided with sp1 ocket wheels 16 that receive endless drive chains 17 operable on the sprocket wheels 3.

Plows 4%) are fixed to plow beamsa'l carried by a plow frame 40, said plow frame being detachably secured to the tractor frame in any suitable manner. \Vhen the traction plow is in service one of the front wheels 1 and the rear wheel?) run in furrows while the other ground wheel 1 rides over unplowed ground.

When it is desired to utilize the tractor as an ordinary motor truck, the plow frame and the single steering wheel are removed and a wheeled attachment B is securedto the rear end of the tractor bbdy, as shown "in-dotted lines, Fig. 2 and in full lines Fig.

3. This produces a truck having a long wheelbase, and a suitable truck bedC may be mounted on the tractor and its attach- 'ment. The' attachment comprises ground side sills 1052.

The short side sills 102 ex tend rearwardly from the rear of the tractor so as to form a continuation of the main side sills at and 4, thereby elongating the tractor body. Springs 105 are preferably arranged between the attachment frame and the axle 106'.

I claim 1. A traction plow comprising traction wheels; a tractor frame adapted to receive a single steering wheel, and a steering device for operating said single steering wheel, combined ,with an attachment extending rearwardly from the rear of said tractor frame, thesaid attachment comprising an extension frame detachably secured to the tractor frame and forming a continuation thereof, and a pair of steering wheels supporting said extension frame, the last named steering wheels being operable by said steering device.

A traction plow comprising 'a main tractor frame, traction wheels and a ground wheel supporting said main tractor frame, said ground wheel b ing detachably secured to said main tractor frame, combined with an attachment adapt-ed to be substituted for said ground wheel, said-attachment 001m prising an extension frame adapted to form a continuation of said maintractor frame, means for detachably securing said extension frame to said main tractor frame, and a pair of ground wheels supporting said extension frame and adapted to cooperate with said "traction wheels to supportsaid main tractor frame.

3, A convertible tractor having a main frame, drive wheels, a ground wheel detachably "secured to said main frame, and a steering device for-operating said ground wheel,

' said steering device being detachably sccure'd'to said ground wheel; combined with an attachment adapted to be substituted for said ground wheel and adapted to extend avheels.

4. A. convertible tractor "comprising a main tractor frame having side sills, traction wheels and a ground'wheel supporting said main tractor frame, said ground wheel being detachably secured to said'main tractor frame; combined with an attachment adapted to be substituted for said ground wheel, said attachment comprising an extension frame having side sills adapted to form continuation of the side sills of said main tractor frame, and a pair of ground wheels supporting said extension frame and adapted to cooperate with said traction Wheels to support said main frame.
